|+||====== PGW World File ======|
|+||[[https://en.wikipedia.org/wiki/World_file|PGW world file]] contains coordinates which terrain builder reads and automatically aligns the imported satellite tiles into correct coordinates.|
|+||Global mapper file -> export raster/image format, normally with "create world file" option, it creates a PGW for each tile like sat_A1.pgw, sat_A2.pgw etc.|
|+||First and fourth lines is meters per pixel (dunno why fourth is negative), last two lines are the terrain builder coordinates.|
|+||You can also create PGW files manually in proper text editor for example if you import L3DT or other source satellite tiles.|
|+||2019-01-20 This worked OK with 40960 resolution satellite on 4 x 4 tiles, but did not work on 5120 or 81920 resolution satellites for some odd reason.|
